Abstract: An image formation apparatus according to one or more embodiments may include: a first conveyer; a second conveyer provided downstream of the first conveyer; a detector that detects a deflection of the medium between the first and second conveyers; a speed controller that controls a speed of the second conveyer within a first speed range; a calculator that calculates an average convey speed of the second conveyer. The calculator calculates a first average speed in a first period from when a leading end of the medium reaches the second conveyer to when the medium is conveyed a predetermined distance from the second conveyer. The speed controller changes, after the first period elapses, the speed of the second conveyer within a second speed range with the calculated first average convey speed as a criteria speed of the second conveyer, based on the detection result from the detector.

Abstract: An image forming apparatus includes (a) a plurality of image forming unit arranged along a transfer medium, each of which is arranged movable between a lower position and an upper position; (b) an estrangement controller to move each of the image forming units between these positions; (c) a print mode management part to determine a designated print mode; (d) an image forming part to select one or more of the image forming units corresponding to the designated print mode, and to form an image to be transferred to the transfer medium by using the selected image forming units; and (e) a correction process part that performs a correction process.
